TUBULAR BELL.

T all whom t may concern Be it known that I, ROWLAND H. MAY- L'AND, acitizen of the United States, residing at Freeport, county of Suffolk,and State of New York, have invented certain new and useful Improvementsin Tubular Bells, of which the following is a clear, full,

- musical note.

The particular object of this invention is to provide a cheap and simpletube of comparatively thin` tubing, thus reducing the cost of the samewithout detracting from the character of tone emitted by the tube.

In carrying out this invention I provide a non-compressible plug ofmaterial thickness, and wedge the same tightly into one end of the tube.I preferably form such plug with tapered sides, so that it may beforcibly driven into place, expanding the tube where it is thusinserted, to cause the tube to be grasped in a strong vise-like gripagainst all liability of dislocation due to the vibration resulting fromthe use of the tubular bell. I prefer to form such plug not only withtapered sides, but with an open center provided with strongsubstantially non-compressible bridge members or webs, which I so locatein the tube with relation to its hanging cord, that a hammer when usedmidway between the hanging cord will strike the-tube adjacent to one endof such bridges, thereby safely guarding against the setting up of avibration which will produce overtone, and whistling, which is a sourceof trouble in light thin tubes.

The scope of my invention will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a View partly in section ofone of my improved tubular bells. Fig. 9. is a top plan thereof. Fig. 3is an enlarged central sectional view with the taper exaggerate-d.

In the drawings, figure l represents a tube of comparatively slightthickness, pr-

vided with openings Q, through which a suspending means, such as thesilken Cord 8 shown, is passed. The non-compressible overtone andwhistling-preventing plug 4 is provided with an annular part 5, having atapered outer side. This plug 4 may well be a casting, and in view ofits applicability for securing in place, it need not be speciallymachined, for as it is tapered, it is adapted to be forced into the endof the tube with substantial pressure, slightly eX- panding the same toproduce the vise-like grip, causing the tube to conform to theinequalities of the surface of the casting. The plug 4 is preferablyprovided with a pair of right-angled cross bridges or ribs 6 and 7.These may not be of the same depth as the collar 5. I prefer to so placethese cross ribs in the tube that there will be one at right angle andone parallel with the cord passing through the holes 2 of the tube. Thisplaces one of the ribs in the direct line for the stroke of the hammer,for to properly strike a tubular bell it should be struck so that it mayfreely swing on the axis of the cord.

I am aware that it has been suggested heretofore not only to load thetop of the tube to prevent overtone, but that it has also been proposedto reinforce the interior of a tube of this description, and I do notclaim such invention broadly.

Vhat I do claim however, and desire to secure by United States Patent,is:

l. The herein described tubular bell of comparatively thin tubing, atapered open plug carried by saidv tubing at one end thereof, aplurality of ribs extending from the wall of said plug to the centerthereof, the depth 0f said ribs being less than the depth of said plug.

2. The herein described tubular bell of comparatively thin tubing, atapered open plug carried by said tubing at one end thereof, a pluralityof ribs extending from t-he wall of said plug to the center thereof, thedepth of said ribs being less that the depth of said plug, said tubing'being provided with openings adapted to receive a suspending element,said openings being disposed in parallelism with two of said ribs.
